postgresql & client

[mikko]

I run into something weird. Is it so, that you cannot have both; the
postgresql server, and postgresql client, installed at the same time?

When I first install one or the other from ports, and after I try to
install the other, I am informed that:

===>  postgresql-client-7.4.1_1 conflicts with installed package(s):
      postgresql-7.4.1_1
      They install files into the same place.
      Please remove them first with pkg_delete(1).
*** Error code 1

and same vice versa.

I am almost certain that I've had both installed.
